Answer:
Desmond's time
Step-by-step explanation:
Given,
Desmond's time (s) 146 292 584
laps 2 4 8
Maria's time (s) 150 320 580
laps 2 4 6
By the first table,
[tex]\frac{146}{2}=\frac{292}{2}=\frac{584}{8}=73[/tex]
Thus, the situation of Desmond shows the proportional relationship between time and number of laps,
By the second table,
[tex]\frac{150}{2}=30[/tex]
[tex]\frac{320}{4}=8[/tex]
[tex]\frac{580}{6}=96.67[/tex]
[tex]\implies \frac{150}{2}\neq \frac{320}{4}\neq \frac{580}{6}[/tex]
Thus, the situation of Maria does not show the proportional relationship between time and laps.
